Well, it is the other way around actually: NASA should not give a flap about MS tooling, and naturally avoid it completely. Whoever thought of having an Outlook or even 2 out of all the things on there should look for another job, because they clearly cannot be trusted with astronaut lives.
Microsoft beleaguered a federal agency which pretends to be a lot larger than it is (and has a lot of help doing it) with nonresponsive filings. The employees of that agency, FedRAMP, referred to Azure as "a pile of shit" but ultimately approved it anyway.
It's hard to find hard numbers (I looked), but in the "FedRAMP over 10 years" chart partway down in this article FedRAMP themselves claims to have approximately 25 employees, which (I infer prior to DOGE) was augmented to approximately 80 staff with contractors.
